Elliot Tiegel is a 17-year-old founder from Washington State who is building OhmLife Insoles from the ground up. Starting with cardboard prototypes and a $100 investment from his parents, he's worked up to a patent-pending product that has charged a phone from footstep energy alone. Self-taught in electronics, circuit design, and 3D printing, Elliot developed OhmLife alongside a full academic schedule, with the support of his mentor and school community. He is the sole engineer, designer, and builder behind every version of the product.
